felimagenoise: An advanced noise generation GIMP plugin1

FelimageNoise is a GIMP plugin, originally developed, to generate noise
patterns, but with feature sizes larger than a single pixel. It can generate
tileable textures, textures for use in spherical mapping. It can use
foreground/background colors, gradients and independent RGBA channels or
warp an image. It implemens several noise functions, such as FBM (Fractal
Brownian Motion) and Multifractal textures, with complete control, to allow
for animation of noise (useful to generate animation frames), as well as
complete presets management.
